Validating International Classification of Diseases Code 10th Revision algorithms for accurate identification of pulmonary embolism.

ABSTRACT:

Background

Many research investigations for pulmonary embolism (PE) rely on the International Classification of Diseases 10th Revision (ICD-10) codes for analyses of electronic databases. The validity of ICD-10 codes in identifying PE remains uncertain.

Objectives

The objective of this study was to validate an algorithm to efficiently identify pulmonary embolism using ICD-10 codes.

Methods

Using a prespecified protocol, patients in the Mass General-Brigham hospitals (2016-2021) with ICD-10 principal discharge codes for PE, those with secondary codes for PE, and those without PE codes were identified (n = 578 from each group). Weighting was applied to represent each group proportionate to their true prevalence. The accuracy of ICD-10 codes for identifying PE was compar
